LINE-CASTING- MACHINE.

Application filed January 1l, 1909.

To all whom 4it mcg; comf'rfi.'

Be it known that l, Jamas licNauauii, of nicntreai, irovinee ci vQuebec,and Dominion ci Canada, have invente-:l a. new and useful` inipiovi-meurin lime-(fasting Machines, of

which the following a specificati ion.

My invention has reference to line casting machines for producingprinted bars or slugs, such, for example, as the machines known tocommerce under the trade marks mouw iine, linotype, ctc. circuiatingmatrices stored in magazines are released in the order in whichcharacters are so appear in print, and assembled or coniposed in lines,together with expansible wedge spacers or justiiiers, the comosed linesbeing transferred to the iace of a s otted mold, where they form typecharacters on the edges of type metal slugs cast successively in themold, after which the matrices and spacers are distributed and return/edto their magazines. ln this class of machines the spacers or justifiersconsist of two oppositel'y tapered connected wedges. After thecompositionvof the line is completed, one wedge of each pair is liftedthrough the line past its companion and past thematrices, for the purose of extending or thickening the spacer wit iin the line, in order toextend the atter to the predetermined llength, this action le1ngteehn1cally known as justiiicationflv ln practice it frequentlyhappens during the composition of aline that one of the members of aspacci' will fail to descend to its pro )er position, and will extendtoo far above the adjacent matrices in the line. When this occurs, theupper ends of the elevated spacers are liable to contact with other)arts of the machine during the transfer of t 1e line, with the resultthat they are injured or broken, and the proper' operation of themachine prevented.

The-aim of my invention is to cause an au- 'tomatic indication ot' thefact whenever a spacer stands above the proper level, andalso cause anautomatic stoppage of the composition.

My invention is susceptible of embodiment in a great variety ofalternative or equivalent forms, which will suggest themselves to theskilled mechanic after reading the following description.

For the purpose of illustration, l have shown my invention applied to amonoline machine ofthe character represented in Let- Specication ofLetters Patent.

Y ters Patent of the United States @605,141 to i W. S. Scuddcr, thearraiigement being such that the elevated spacers act to unlatch the`transparent door covering the channel through u hich the matricesdescend to the line, so that further composition is impossible.

Referring to the accompanying drawings: Figure l is a front elevationshowing the parts-by whichthe line is assembled, with my improveddevices applied thereto,-the parts being in their normal or operativeposition. Fig. 2 is a similar view, illustrating the manner in which anelevated spacer'acts to unlatch the transparent door. Fig. 3 is ahorizontal, section onthe line 3 3 of Fig. 2. Fig. 4 is a sideelevation, showing the spring by which the door is automatically openedafter being unlatchedf. Fig. 5 is a view of one ofthe spacers. i l

Referrin-or to the drawings, 12a representsv the vertica transparentdoor behind which the matrices and, spacers descend to the end of theline in course' of com iosition.; The door is hinged at the right e ofe,so that it may swing around horizontally, and itservest to close thefront edge of the channels through which the matrices. and spacersdescend and assist in guiding them to the line, so that when o en theaddition of further matrices to the ine is prevented. The door is heldnormally ina closed position by a latch bar 12b, having oblique slotsthrough which tion being such that the latch or slide defscends bygravity toward the door so as to overlap its edge and hold it closed,las shown in Fi 1.

Sogfar as described, the parts may be constructed and arranged tooperate in all respects like the parts indicated by the same letters inthe' patent above referred to.

In carrying my invention into effect, I

ass retaining screws, the construc- Inount in the frame a'horizontalsliding npin a, bearing at one end against the inner facel of the doorand urged constantly forwardby a spring al, so that when thedoor isunlatched by the rising movement of the sl0t ted bar-12b, it will beautomatically thrown open, as shown in Fig. 3. The matrices C,

which are carried in the usual. magazine are` released one at a t'imeand descendbehind the door to the end of the line which isbeingcomposed, suitable devices being provided-to assemblethe matn'cesand spacers side byf successive matrices or spacers are added to thedine, it is pushed forward to the left by the ejector slide 62, as inthe original ma* chine. Each spacer' Dshould settle down in the line tothe level shown in Fig, 1, but it Will sometimes happen that a spacerwill remain at a higher position, asshown in Fig. 2. For the pur ose ofcausing these elevated spacers to re ease the door 12a, I provide thelever E, pivoted to the frame at e, and arranged to bear at e1 beneaththe latch 12".

This lever has a downwardly extending end with a vertical flange e2, insuch position that Whenever an advancing spacer in the Iline standsabovethe proper position, the shoulder d of the spacer will encounterthe flange and move the lever from the normal position shown in Fig. 1to the ositionshowni Fig.

2, thereby liftin the s ide 12b and re, asing the door 12, W ich isimmediately/thrown open as shown in Fig. 3 by the spring before referredto. When the door is t ius opened, further composition is impossible,and the operator is compelled to push the spacer down to its ro er placein the line' and close the door befldre e can proceed with his oper.-ation. A y It will be erceived that my contrivance serves not on y as anindicator to'warn the operatorpf an improperlfy placed spacer, but a soas a stop to prevent urther composition.

-'It Willbe (ibvious to the skilled mechanic thatthe devices may beconnected with the usual Stop mechanism of the machine, if desired,ftopositively prevent continued oper- 'to ho d the door closed means to suation of the machine, or of any desired'part ofthe same.

In the form shown the parts act both as an alarm or indicator to callthe attention of the operator to the improper position of the spacer-and also as a means of positively preventing additions to the lineu'ntil the spacer is in the proper osition.

It will be understoo that both the mat'- rices and s acers may be ofrany practical form, and t at my stop devices may be actuated byelevated matrices aswell as by the s acera-the lever E or its equivalentbein sila ed and located in each case, as the skil of t Ve mechanic Willdictate, to correspond with'the other arts.

It is to be o served that" my device, although compelling aninterruption of the composition, permits all the operative parts of themachine to continue in action` Having thus described my invention, whatI claim is:

1. In combination with the hinged door to aid in guidin matrices to theline in course of composition, means controlled by highs paces-in theline to cause the opening of the door.

2. In combination with the hinged door, a-

sprin connection to openl thesame, a latch' port the composed line, andmeans operate members in the line to disengage the latc 3./ Incombination means to support the composed line, the ldoor litsconfining. latch, and the latch operatin lever arranged to be p peratedby high mem ersin the composed '1ne. A .In Atestimony whereof Ihereunto'set my hand thisfourth day of January,V 1909, in the presenceof two attesting witnesses.
